Light Spots
I have a couple of wooden chess computers that have the dreaded light spots where the chess pieces were allowed to sit for an extended period causing the color change.
But why? Is it because the ambient light is causing the whole wooden board to change color except the areas under the chess pieces? Or, is there a reaction between the finish on the wood and the felt on the bottom of the chess pieces? Or....?
Is there any danger of creating light spots by leaving chessmen on a wooden board overnight? Over a few days....or a week? Currently I don't leave chessmen on a wooden board unless I am playing a game.
Thoughts?

Re: Light Spots
I believe that our closest star is the top "Most Wanted" for such a shady crime. I don't have any wooden computers which have developed "sun-spots" in my possession, but I have always tried to stay clear of prolonged periods of sunshine upon the boards and especially on pieces that are set-up. I had some of the wooden computers in a public exhibition (for two months) a couple of years ago. The area was sunlit for only some smaller period of time during the day, but I took the cautionary way of not setting up the pieces on the board for the Expo.Dave C wrote:I have a couple of wooden chess computers that have the dreaded light spots where the chess pieces were allowed to sit for an extended period causing the color change.

Is it just my pieces, or are by the way, Saitek Reinessance pieces very pale in comparison with for instance Mephisto's?

Hi Dave
Unfortunately I can't answer your question but why don't you try this from Berger's repair site.

Hi Dave,
I have the same problem. Haven't done anything about it yet, but I did get a tip from a fellow collector:
Take a piece of paper, the same size as your board. Make holes in it at the positions where the light spots are (where the pieces had been positioned). Cover your board with it, and expose it to daylight for a number of days. It may take weeks or longer, but he says it has worked in his case!
Sunny daylight regards,
Paul

If I am mistaken, it must be caused by a horizon effect...

Hi Dave,
I'm not sure it's the sunlight that does this. Tony has an interesting theory and a great method to clean the board. I've used this method on my Tournament Machine which is now as good as new. I've ever left the pieces on the board after play.

Re: Light Spots
A number of years ago I purchased a DGT board and chessmen. At that time I asked DGT if leaving the chessmen permanently on the board would discolour the board squares.Dave C wrote:I have a couple of wooden chess computers that have the dreaded light spots where the chess pieces were allowed to sit for an extended period causing the color change.

Their answer was no. The chessmen would not affect the surface of the board squares but sunlight would. So I kept the board and chessmen covered with a thick dark cloth when not in use. It worked. My board has no light spots.

Under 2 I read "don't worry about the fluids leaking in around the Leds??
Come on... It takes 5 minutes and a few screws to separate Board PCB from the board...
